my circuitboard in the rear of the frig is clicking.I can unplug the frig or turn the knob to the off position then repower and all the components will come back on. the lights never go off during this problem. when everything is running fine and you try to get water or ice the light in the area where the ice and water is located dims down after the trap door for the ice closes the light brightens to normal the evap fan dies down also. I disconnected all components the clicking continued until i disconnected the evap fan. when i pluged it back up the clicking stopped.everything went back to running fine. after a few hours the whole thing starts over again.

I checked the circuitboard front and back it showes no sighns of burns or breaks in the solder. also the evap fan continues to run when you turn the freezer switch to zero the compressor stops.
